Description
(-)-Epicatechin is a flavan-3-ol reference material offered as ROTICHROM® CHR at min. 90 % purity. It is identified by CAS number 490-46-0, EG nr. 207-710-1 and the empirical formula C₁₅H₁₄O₆, with a molar mass of 290,27 g/mol. This phytochemical is used as a chromatography standard and in analytical work on polyphenols, natural products and related plant secondary metabolites. The compact 500 mg glass pack supports precise weighing for calibration solutions, method validation and comparative studies without unnecessary surplus. Supplied from manufacturer Carl ROTH under the ROTICHROM® CHR line, the material provides a defined identity for laboratories building or maintaining chromatographic reference sets. Clear reporting of purity, formula and molar mass aids documentation in analytical chemistry and phytochemical research. The glass presentation is practical for controlled storage and repeated sampling in HPLC, TLC and other separation techniques that rely on authentic catechin-type standards.
This article is part of Chromatography standards (GC, HPLC, pesticides), in Analytical standards & reference materials.

Questions about (-)-Epicatechin, ROTICHROM® CHR, 500 mg, glass
What is this article?
(-)-Epicatechin, ROTICHROM® CHR, 500 mg, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Chromatography standards (GC, HPLC, pesticides), inside Analytical standards & reference materials, in Lab chemicals.
A chromatography standard is the substance, or the mix, injected so a peak can be named and quantified. Pesticide mixes, residual-solvent mixes and single-compound standards are different articles. The concentration and the solvent are the specification. The solvent has to be one the method may contain.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
